Sine Function
The sine of an angle is always the ratio of the (opposite side)/(hypotenuse).
  Sine of ABC=AC /AB
  (opposite side)/(hypotenuse)

Cosine Function
The cosine of an angle is always the ratio of the (adjacent side/ hypotenuse)
The cosine of ABC =CB/AB
(adjacent side)/(hypotenuse)

Tangent Function
The tangent of an angle is always the ratio of the (opposite side)/(adjacent side)
The tangent of ABC =AC/ CB
